In "The Outsiders," what year did Johnny Cade die?

Hinton does not specify what year Johnny dies. There are some general hints—it's after 1960, because the other boys drive a Corvair in the early pages, and that wasn't made until 1960. Paul Newman started being really popular after movies in 1961 and 1963, and the book came out in 1967, so I'd bet 1963-1965.
